MPU Board*:

Newly designed board is currently in development and testing.

This completely redesigned board will replace Williams System 9, 11, 11A, 11B, 11C.

Our boards are plug-and-play compatible with the original board set. No special tools or mounting tricks are required and the swap can be done by even the most novice of "installers".

Benefits over the original Williams board:

- Williams WPC type mounting holes for ease of install / uninstall.

- No batteries required for memory retention (no acid damage, ever!)

- Simplified driver design using logic level FETs

- Beefed up switch matrix drive for better durability (good to 100V back drive)

In addition:

- Board is made with 100% through hole components.

- No custom parts used in this design (all parts can be purchased through usual suspects)

- Major component designators carried over from original design so original schematics can be used.

- Board comes with complete set of schematics
